PLATE ATTACHMENT FOR EXHAUST MANIFOIJDS.

Application filed December 5, 1921. Serial No. 519,855.

T 0 all whom it may concern:

Be it known that we, JoHN E. ALEXANDER and WALTER G. citizens of the United States, and residents of the city of Port Edwards, in the county of lVood and State of Wisconsin, have invented certain new and useful Improvements in a Plate Attachment for Exhaust Manifolds; and we do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, and to the numerals of reference marked thereon, which form a part of this specification.

This invention relates to improvements in attachments for automobile engines especially adapted for use with the carburetor and intake manifoldof the same.

One of the objects of this invention is the provision of means which may be readily applied to any automobile having the intake and exhaust pipes on the same side of the engine and which will act to heat the intake manifold by means of the heat radiated from the exhaust pipe whereby a better .combustion mixture will be obtained.

Another object of this invention is the provision of a heating device for automobile manifolds which is especially adapted for use with automobiles and which may readily be applied thereto with a minimum of trouble and without the necessity of any ex- I tra parts.

Another object of this invention is to provide a housing for the manifolds which can be made of sheet metal by stamping.

A still further object of this invention is the provision of a unitary device adapted to be used in connection with separate exhaust and intake manifolds whereby the same may be made to function as a unit and the heat radiated from the exhaust pipe during the operation of the engine be directly trans ferred to the intake manifold to better vaporize the incoming mixture.

Still another important object of this invention is the provision of an auxiliary heating device for internal combustion engine manifolds which shall be simple of construction and readily and cheaply manufactured whereby the same may be used with a minimum of expense, and which article moreover is of neat appearance and can be ap plied by anyone within a very short space of time and with practically no trouble or labor. Another important object of this inventron is to provide a casing to fit over the intake and exhaust manifolds of an engine and to furnish such a casing with a means for heiiting these manifolds when the engine is co It is a further object of this invention to so locate the supplemental heating means that the heat supplied thereby will be confined by the casing and conducted to the manifolds.

Other and further important objects of this invention will be apparent from the disclosures in the accompanying drawings and the following specification.

The invention (in a preferred form) is illustrated in the drawings and hereinafter more fully described. I

On the drawings;

Figure 1 is a side elevationof an automobile engine of the Ford type showing the improved device. of this invention as applied thereto.

Figure 2 is an inside view of the attachment.

Figure 3 is a top View of the same.

Figure 4 is an end view of the device.

Figure 5 is an enlarged sectional view of the heating device taken on the line 55 of Figure 4:.

As shown on the drawings: 7

The reference numeral 10 indicates an automobile engine having an exhaust pipe 12 and an intake manifold 14: thereon of ordinary construction.

The intake and exhaust manifolds are covered with a casing 16 of sheet metal or other sheet material. This casing has a main face 17 which slopes upward and backward in order to afford space for the valve cover below and closely fit the engine block above. The edges of this casingare made by flanges 18 each of which has a shoulder 19 tofit the shoulder of the engine block. The edges of the face 17 which are furnished with 100 the curve of the exhaust pipe as shown at shown at the left in Figure the right in Figure 1. At the upper end of the flange 20 the edge of the face 17 has a shoulder 22 and then a curved portion 23 which accommodate the seat of the left hand bolt 28 and fit the shape of the exhaust manifold. The straight edge connecting the curved corners 21 and 23 lies against the side of the exhaust'pipe along the length thereof.

The bolts 28 are those which attach the manifolds to the cylinder head. Three of these pass through the holes 26 in the casing 16 but the fourth or left hand one in Figure 1 passes outside the flange 20. The

clamps 30 which are provided to enable the bolts 28 to hold the manifolds in place are located on the outside of the casing and serve to hold the casing in place also.

In order that the upper part of the face 17 may lie fiat against the exhaust manifold, there is an-an le between'it and the oblique partas shown at 2 1.

The two flanges 18 do not meet at the bottom of the device but are separated by asmalldistanc'e. The edges of this space are rounded as shown at 31 in order to fit well against the intake manifold. just above the carbureter as shown at 32 in- Figure 1. The inner part of the passage between the flanges 18, which isthe lower part in Figure 3, is occupied by a box The outer and inner sides of 'this'box are single Walls of sheet metal but the other two side wallsare made double as shown at 34 in Figure 5, and the upper parts of these walls are turned parallel 'to flanges 18- "to afford flanges 35 and 36 above and below the flanges 18 respectively. The box can be secured to the casing by sliding it into' place, the

flanges 35 and 36 clasping'the lower edges of the flanges 18. i

In the bottom of the box is placed asbestos or other absorbent material:as shown at 37 and this is secured" in placeby having a piece of wire gauze 3 8 pressed down over it. The gauze fits the sides of the box closely enough to hold it against the asbestos. A hole 39 in one of the'double sides ofthe box affords access to the absorbent.

In order to attach the casing to .anengine, the box 33 is first slipped out. Then the nuts are removed from the bolts 28 and the clamps 30 removed The casing is then placed on the engine, the passage 40 being slipped over the intake manifold and the I holes 26 over three of the bolts.

The clamps 30 and the nuts are then replaced and the nuts tightened. Finally the box 33 is slipped into the outer part of the passage 4:0. The outside of the casing be japanned or lacquered as desired.

It will be seen that hereinis provided an attachment for automobile engines which may be readily applied and which is ofvery inexpensive construction and may be mantemperature of the manifolds.

ufactured in great quantities by an ordinary stamping process, thereby rendering it readily adaptable for use upon all engines which are equipped with separate exhaust and intake manifolds by only slight Variations in the shape thereof.

When the engine is running, the exhaust The great saving of fuel will be apparent from the use of this device,- as the same is' more readily vaporized on account of the heat which is directly conveyed to the intake manifold from the exhaust pipe by means of this arrangement;

'- When the engine is not running and the heat that should come Jfromtheflexhaust manifold is lacking, it is desirable before attempting to startthe engine that the tem perature of the inlet manifold be raised. I For this purpose the operator puts some "gasoline, alcohol or other inflammable liquid on the absorbent material37 and sets fire "to it. This is most conveniently done by using a can likean oil can to introducethe inflaminable liquid through the hole 39 and then the heat generated is confined within the we ing 16 and so goes almost Wholly to raise the manifold is thus brought to a temperature that in ures the vaporization of the gasoline drawn from the carbureter and so makes easy ,and certain the starting of the engine;

The intake "Heretofore, only the more expensive auto-i nmobileshave been equipped with integral intake and exhaust manifolds, owing to the difficult and costly construction, but by means of this -device,the carburet-ers on the cheaper grades of carscan be made to 'operate as efficiently as if employed with the more expensive double manifold.

We are aware that many changes may be made andnumerous details of construction varied throughout a wide range without departing from the principles of this invention, and we therefore do not purpose limiting the patent granted hereon otherwise than necessitated by the prior art.

We claim as our invention: 7

1.. An auxiliary heating means for an intake manifold comprlsing a unitary sheet metal plate having holes 1n the plate adapted to co-operate with clampmg bolts upon the engine and integral inwardly turned flanges extending around portions of the edge of said plate, said flanges formed to cooperate with portions of the engine adjacent the intake manifold to snugly house the With said fuel holder for detachably securing it to the casing.

In testimony whereof, We have hereunto subscribed our names in the presence of two 15 subscribing Witnesses.
